I want to spilt Alphanumeric with two part Alpha and numeric with special character like -

string mystring = "1- Any Thing"

I want to store like:

numberPart = 1 

alphaPart = Any Thing

For this i am using Regex

Regex re = new Regex(@"([a-zA-Z]+)(\d+)");
            Match result = re.Match("1- Any Thing");

            string alphaPart = result.Groups[1].Value;
            string numberPart = result.Groups[2].Value;

If there is no space in between string its working fine but space and symbol both alphaPart and numberPart showing null where i am doing wrong Might be Regex expression is wrong for this type of filter please suggest me on same

Try this:

(\d+)(?:[^\w]+)?([a-zA-Z\s]+)

Demo

Explanation:

  • (\d+) - capture one or more digit
  • [^\w]+ match anything except alphabets
  • ? this tell that anything between word and number can appear or not(when not space is between them)
  • [a-zA-Z\s]+ match alphabets(even if between them have spaces)

Start of string is matched with ^.

Digits are matched with \d+.

Any non-alphanumeric characters are matched with [\W_] or \W.

Anything is matched with .*.

Use

(?s)^(\d+)\W*(.*)

See proof

(?s) makes . match linebreaks. So, it literally matches everything.
